Details are emerging about President Obama's Oct. 15 visit to San Francisco, and it's all about the bottom line: This is his can't-miss shot to boost the Democratic National Committee and Organizing for America bank accounts in a city that's a faithful Democratic ATM.

The fairly traditional fundraising event at the St. Francis Hotel is already a hot ticket. Organizers have booked the tony hotel's largest venue to accommodate the hundreds of eager Dems who will line up to write their checks and hear the O in person.

Want in? Get ready to part with $500 to get into the reception and $1,000 for a seat in the VIP section.

Neither the White House nor the DNC are releasing details, but insiders say that the San Francisco event could put as much as $3 million into the Dems' fundraising kitty.

This looks like a fly-in, fly-out trip. Obama is unlikely to do any public events in our fair city, a guaranteed magnet for protesters both left and right leaning.

As for all those who have suggested Obama will make a surprise stop at the Presidents Cup golf tournament at Harding Park this week? Sorry, folks, not gonna happen.

A healthy debate: On the very day the U.S. Supreme Court asked the Obama administration to weigh in before deciding whether to hear the case against San Francisco's universal health care plan, Sara Rosenbaumwas teaching her students about it.

She heads the Department of Health Policy in the School of Public Health and Health Services at the George Washington University Medical Center in Washington.

We caught up with the professor Tuesday to ask her about the case. (A refresher: The local restaurant association has sued over the city's mandate that employers pay for health care and wants the Supreme Court to settle the matter.)

Rosenbaum said the case deals with "an enormously important question" - whether a city has the authority to impose financial obligations on employers when it comes to health care.

She said the court wants to see what the Obama administration thinks, because it has been curiously silent on the legal matter. But if she had to bet, she'd predict a win for the city, which has already been supported by a federal appeals court.

"I would actually be somewhat surprised if (the Supreme Court) took the case," she said.

Scuffling over sanctuary: Supervisor Chris Dalymade a guest appearance this week at the Board of Supervisors' Public Safety Committee to support changing the city's sanctuary ordinance so that juveniles accused of felonies won't be turned over to federal immigration authorities - at least not unless they're convicted.

Daly used the opportunity to rail against Mayor Gavin Newsom, saying he should be "held accountable for releasing a legal memo that said the proposed policy change would invite lawsuits and possibly threaten the entire sanctuary policy."

Daly downplayed the memo, saying it outlines a worst-case scenario and "exaggerates the legal risk involved." But he also said that Newsom, in releasing the document, had provided a road map to anyone looking to challenge the ordinance.

"It really, really hurts the city's case in court," Daly said.

Newsom "has no regrets," said his spokesman, Nathan Ballard. "The reason that Chris Daly is howling about the release of this memo is that even he realizes that it spells out what a bad idea this bill is."
